If you have even heard of this movie then you likely have already seen it and it was a long time ago. Nostalgia is the only valid reason to watch this film. While it seems to have been forgotten by British TV it has resurfaced on YouTube.
The reviews are mixed between rose tinted nostalgia and flat out hatred for what is a very shoddy piece of work.
This was made by veteran director Val Guest, so why does this Cannon and Ball vehicle stink? I think the answer is Cannon and Ball. Now while they are experienced comics they simply cannot act. There are brief moments which are funny when they are doing what is there stage act while being filmed, but the majority of the film is them trying to act out scenes and cover the story. They simply aren't up to the job of an actor and it sucks the enjoyment out of the film.
It looks like but was filmed on a shoestring budget and there are a few action scenes which are actually pretty boring.
They must have spent a fair amount of the budget on the dodgy theme song at the end which if I recall was released as a single?
Unless 1970s comedy is your thing, in which case you are likely in your 70s or 80s the humour is unlikely to appeal. Things like looking up a woman's skirt while she is on a ladder etc is the level on offer.
You can only recommend this for people who want a second exposure to this movie not having seen it since 1982. There's a pretty good reason why it's not troubled the airwaves since then unlike many other 80s comedies. Although I'm sure with the passing of Bobby Ball this week it will get a few viewers. Now all I need to do is figure out how to delete all those Cannon and Ball recommendations on YouTube I have been lumbered with after sitting through Boys in Blue.....
